'TANK-CARRYING-BOX-CAR WITH TRUSSED UNDERFRAME.

1 Application filed December 24,' 1915.

To all i/'Lo/n, 'It muy concer/t:

Be it known that I, Amies E.' Os'rimxnic, residing at ltidgmvood. lergen county, New Jersey, and heine; a citizen of the. United States, have invented certain new and useful Improvements in T aiik-Carrying Box- (`ars with l`russed llndert'rames, ot' which the t'ollo\\'iiig is a ilull, clear, and exact description, such as will enalile others skilled in the art .to which it appertains to inake and to use the saine` reference lieing had to the acconipanyingidrawings7 which illustrate the preferred form of the invention, though it is to he understood that the invention is not limited to the exact details of construction shown and described, aslit is ob-V vious that various inoditications thereof willv occur to persons skilled in the art. In said i :i horizontal section somewhat,above/the floor line, the tank heilig Vomitted in both lialves. f.,

The invention herein disclosed relates to hox cars in which one or nioi'e tanks for thiid lading are mounted and inclosed. .As the'tank or tanks are housed in the hox cai' superstructure the car is adaptedA to the conveyance ot' fluids comparatively easily eoiigcaled in the winter season. Liquid that is suhject to rapid volatilization under the influence olA heat may he transported in my improved car. Such liquids will he protected from the heat ot' the sun during the Specification of Letters Patent.

warmer seasons o't' the year and in clinics where the temperature is normally excessively great. Due to such protection, dan gcrous vapor tension will not develop within the tankas would otherwise he the case in connection with some types ol' intlannnahle fluid ladings. ,f

A meritorious construction is present in the head hlocks for the tank which permits a ine`adjnstiiieiit ot the head lilocks with reference to the tank and prevents to an unusual'degree longitudinal shitting ot the tank. A bed is provided tor each tank and is designed to relievey the thrust of the tank againstdts head hlocks. Simple and ellicientnieans are provided t'or mounting the head hloeks and is readily constructed from commercial material.

Those heavy loads imposed hy liquid ladings are amply and uniformly sustained by the strong underfranie construction that is provided. The undert'rame is trussed and the truss rods are ingcniously anchored in the head hloeks tor the tanks. `Struts are employed as queen posts in the trusses and enter into the cross hearer construction in such manner as to contrihute to the strength of the under-traine to a niuch .greater egvtent than struts usually do. Other ydesiralole features will heeonie apparent hereinafter and a re parts of the present invention. y

Referringr to the drawings, l indicates the center sills of the car heini; sliowli as com mei-cial channels with their llaiiges inturned and which. extend through and heyond the holsters. Spliced to the ends ot' center sills 1, and extendingr to the end sills 2, are channel-shaped Adrat't sills 'lhe usual dral't j {ear stops 4 are secured to the. inner faces ol' the di'itt sills fl, while the outer ends olt the dra'ft sills il ahnt the end sills 2, and the/latter are cut out, lor the passage of the draw liar (not shown) olI the draft gear.

Side sills 9, in the forni of channels having inwardly extending flanges, arc snppol'ted b v the outer ends ot' the end sills 2, bolsters G. cross bearers 7 and floor beams 8 and 8a. The connection between the terminals of side sills 9 and the end sills 2 is el:- fected by connection angles 10 and horizontally disposed gusset plates l1. (See Fig. 2.)

Bolsters 6 are ot' the built-up type. as shown in Figs. 2 and 2l. llacli bolster luis a pair ot' spaced web plates l2. located on each of the opposite sides ot' the center sills 1, only one halt' otl the bolster being .shown in the drawings. The upper and lower edges ol' each web plate are outlined on their outer faces by top and bottom chords 13 and 14, respectively, both chords being angles. x

The vertical edges et' the bolster webs are stiffened by other angles, the inner angles 1,5 serving as connection iiieuibcrs between the holsters and the center sills l. Outer angles 1G act as connectors between the holsters and the side sills 9.

Top'cover plates 17 span 'the spaced top chords 13 ot the bolster and extend from av line somewhat inset troni the top flange ot' one side sill 9 across the top flanges of the center sills l and to a similar line equally removed t'roin the top flange ot' the side sill on the opposite side ot' the car. Bottoni cover plates 1,8 extend substantiallv the entire length ot' the bottoni chordsl l-l ot' one pair of bolster webs 12 underneath the bottoni flanges ot the center sills l and along the entire bottoni chords 1-l ot' the bolster webs l2 on the opposite side of' said center sills.

The usual side bearings 19 are firmly se cured to the underside ot' the bottoni cover plates by rivets passing through flanges of' the side bearings, bottoni cover plate lh and the outstanding bottoni flanges ot' bottoni chords 14. Alsosecured tothe under l'aceot bolster. llaving a bottoni flange 22' resting upon the upper surface of bottoni cover plato lf2, between flic bottoni flanges ol' the center ``iills l, isa bolster center filler provided with .t cylindrical socket 2l for the usual king pin. Flange 22 ot' the bolster center `filler is shaped to (he upper surl'ace ofthe bottoni flanges of center sills l and is upturned to parallel the inner t'aces ot said centersills to lorni aftacl'uuent flanges 23. As 'indicated in Fig. 3 at lhevright, rivets pass through the flange portion 23 of the center bolster filler, the web ot the center sill and through Other one leg ot' the'eonnection angle 15.-

rivets passI through the bottoni flange 22 of` said bolster center filler, the bottoni langes of the center sills and the flange ot' the center bearing plate 20. Diagonal fbraces 24 (seen in Fig. 1) are riveted to topv cover plates 17 on opposite sides of the centei'sills and each rims obliquely to one of the gus- .neet'ed to the-center sills. vcomprises webs 25. one on each side of the 80 .center sills each provided with top and botthe center sills 1.

The next transverse underframe member encountered in proceeding toward the center of the car, is a Hoor beam 8, serving the same function as floor beams 8 but being modified to accommodate a supporting structure for'the inner tank head blocks and will be described more in detail in connection with the description of these head blocks.

Center sills l and side sills9 are provided with floor Stringer supports. Those carried by the side sills 9 are angles 40, preferably 'co-extensive with the sills, and secured to the outer faces of the vertical webs thereof. The fioor stringer supports borne by the center sills l are on the outer faces of the webs of said center sills, but, as indicated in dotted lines in Fig. l, are short'angle pieces 4l spaced along the center sills at suitable intervals and riveted thereto. Floor stringers 42 are supported upon the side sill Stringer supports 40 and may have the same length as the side sills themselves, while Hoor stringers 43 are carried by the center sill floor Stringer supports.

The Hoor boards 44 are nailed to said stringers, and, as shown in Fig. 3, extend from one outside Stringer t2 to that on the opposite side of the car, resting upon the stringers which derive their s upport from center sills 1.. Extending transversely of said floor boards 4J: and longitudinally of the car are timbers l5 of substantial cross section, these timbers being arranged in co` upper surface curved or otherwise shaped i to adjust itself to the curvature of the tank sheets 47. As indicated in Fig. 1, the tank sheets 47 each comprises a comparatively short cylinder, having annular flanges delineating the perimeter of the circular bases.`

Said flanges of adjoiningr tank sheets are secured together either by rivets or bolts and the end flanges of the end tank sheets of an accumulated series of said cylinders. form attachment means for tank heads -lS which may also be. riveted or bolted into place. lith this type of tank it is apparent/that tanks may be quickly and easily assembled to sllit the length of any car in which itis desired to install them. Also sinlilar tanks may be assembled in desired lengtfhs and arranged in any convenient series within a car of the type herein disclosed.

Adjustable, head blocks are prbvided for cach outer tank end and each comprises a rugged casting 4Q, having a base 5U and a crescent shaped pocket portion 5l., being con- -the impingement of the tank head 4s being against a wooden block 54 retained by angle 55. The wooden block 54@ and its retaining angle 55, are conformed to the crescent shaped pocket portion 51 of the tank head block casting and are so fitted thereto as to be slidable to a greater or less extent either farther into or out of said pocket, whereby the blocks 54 at opposite ends ofthe tank,

may be adjusted to thelength of such tank.

The adjustment of blocks 5ft is conveniently and reliably made by a plurality of wedge keys 56 in each tank head block, one of said wedge keys being shown in Fig. 5 to extend through slots of greater width than itself in the upper and lower walls of pocket portion 51 of the head block casting. Said key has an inclined surface that bears against an inclined face 5T in the top wall of the pocket portion 51 and against another inchned face 58 winch constitutes the edge of `a wall intermediate, but parallel with the upper and lower walls of said pocket 5l.

The lower end of key 56 is made cylindrical,

as shown at 59 in Fig. 5, said cylindrical portion extending through the slot in the lower wall of pocket 51 and being provided with adjustment nuts 60, the inner one of which bears against a suitable washer lying against the lower wall of said pocket 51. It is clear from the construction shown in Fig. 5 that, by adjusting nuts (50 in the proper direction. key may be moved either farther inwardly into or outwardly from said pocket portion 51'. and that, when so moved the angle which retains the wooden or other block 54 may be correspondingly moved into or out of the pocket in`a direction parallel to the longitudinal axis of the tank. Thus adjustment of the head blocks to the tank heads is easily made with no more dilliculty than is requiredby the ordinary application of a wrench.

The flanges at the joints of the cyliiulrical tank sheets 17 occupy the depressed portions of pressed metal channel members (51,]wh`ichr are inset in the upper or curved surr'acey of said tank bed timbers 45. Such insertion of the flanges of tank sheets 47 into the grooves of channel members (il serves to restrain the tank from longitudinal movenuplt in either direction and prevents the total force of an end thrust being delivered lniinediately to any one of the tank head blocks. Channel members (31, therefore, also operate as a series of longitudinally vspaced unycsely, each is braces 24: and 'as said su )aol-timT 7 i a yielding tank anchors arranged onboth sides of the vertical center line of the tank. 1t is obvious that channel members 6l could be omitted and the grooves in the tank bed timbers 45 could be of less width, whereby the flanges of tank sheets 17 would be adapted to f foperatc directly with the walls of said grooves. ,This, however, would subject the wood fibers of such walls to undesirable at-` trition, and it is considered preferable to insert the unyielding metal channel members (i1 to protect the walls of the grooves in tank bed timbers 45.

The underframe is given a trussed construction which adequately supports the weight of the tank or tanks and their ladings. Truss rods (52 are arranged in substantially parallel pairs on opposite sides of the transverse center ofthe car. One end of each of said rods passes through a cylindrical socket 63 integral with the base 50 of the tank head block casting at one end of the car. Extendingr toward the car center, each of said truss rods (32 lies in a semi-cylindricallseat of a truss rod saddle, being provided foreach pair of parallel truss rods (32, and each saddle being secured to the upper surface of the bolster 6, or, more premounted on the upper surface of thetop cover plate 17 of the bolster 6. As shown in Fig. l, truss rods 62 are deflect` ed downwardly after passing through their saddles 64, and continue in an oblique direction until they encounter semi-cylindrical seats in the strut casting G5, from whence the truss rods (32 continue in a horizontal direction to substantially the longitudinal center of the car. ered and the opposing .ends thereof are threaded to receive an adjusting turnbuckle (3G. Only one half of the car has been shown, but it will suffice to say that, in. extending to the opposite end of the car, the truss rods are reversely bent and in reverse order are seated against a similar strut and in similar truss rod saddles 64. on top of the bolster at that end of the car, continuing to the head block at that end, where they are secured in exactly the same manner as that shown in the l illustrated car end. Truss rods GQ'are not only adjustable by the turnbuckles G6, but have their opposite ends protrude from the cylindrical sockets (33 of the head block casting, said truss rod ends being threaded to receive adjusting nuts (57.

The base of the head block casting at each end of the car is mounted upon a supporting plate or platform 68, which has an upturned flange (39 riveted to the web of the end sill 2, said platform extending under base plate 50 of the head block. Supporting plate or platform (38 has its rear corner portions mounted upon the diagonal plate (58 f rests upon the draft sills 3, it isrmly and one such saddle The truss rods 62 are here sev- Lazer/re solidly retained in place and is well adapted to support the hea-d block at the end of the CHI. l

more than one tank is blocks, each provided with a base employed. Base 50rl i s principally from base 50 in that the cylindrical sockets (33 are not present and the head blocksfcontaining the base 50a are for the inner ends of the tanks. The remainder of the construction is similar to the other head blocks previously described, and corresponding numerals are applied to the corresponding parts.

The base platesO of the inner head locks are mounted upon the top cover plate G9 of the center sills l and also upon fillers 86 lying upon the upper surfaces of the top flanges of intermediate sills 70, which llers are co-extensive with the width of the base 50a. The comparatively short intermediate sills extend between cross bearers one of which is shown), and pass through floor beam 8a, as shown in Fig. 4. Floor beam 8 is provided with top and bottom chords 26rl and 27, respectively, riveted to the upper and lower edges of floor beam 50a, are

web 25a. Connection angles 29a connect web 25a to the side sill 9, and connectlon angles 28 connect said web 25a termediate sills 70. A diaphragm 7,1 is connected to the opposite face of intermediate sill 70 and to the center' sill 1. Top and bottom cover plates 3la and 32, respectively, extend across the top and bottom flanges of the top and bottom chords 261'and 27, the upper and lower flanges of intermediate sill 70 and of diaphragm 71, and also the upper and lower flanges of the center sills 1, continuing .in like manner to a corresponding point at the opposite side of Hoor beam 8a.

'Center sill supported stringers 43 are interrupted by the interposition of the tank head blocks having the base plates 50, but

In ears of the type illustrated, in which I housed, inner heady different Y 7 (only tothe web of in- 73 secured to the outer faces of the short ini termediate sills 70 within the longitudinall limits of the interruption of the center sill supported Hoor'stringers 43.

The floor boards 44 may, preferably, be fitted about the base plate 50a of each of the inner head block castings and be properly supported while leaving an appropriate open area for the occupancy of said 50a. She-rt intermediate sills 70 each have their end portions secured to the webfplates 33 of the cross bearers 7 and, therefore, each derlves its support from sald cross bearers and from the door beam 8a through which it passes end forms a part.

Each entire cross beare' and the strut casting embraced thereby. therefore. becomesl a strut adapted to act as a king or queen post. The truss rods become tension members of the truss and the drat'l sills and center sills connected therewith become compression members ot' the truss. said truss giving ample support to the tank and its ladine., vAny tendency ot' the center sills to the weight of the tank or tanks mounted in the car, the structure illustrated being a wellbalanced one so far as the resistance to buckling stresses is concerned.

The tank is also maintained in position by the tank bands indicated at T5 in Fig. Il. which are secured Vat their lower ends to adjusting rods Tt). 'l'h-e lower ends otl said rods extend through a tixedly positioned casting Si and are provided with adjusting nuts S5. whereby the tension of tank bands 75 may beregailated. 'l`he tank is also stayed or anchored by adjusting rods TI. the lower ends oi which pass through castings 7S mounted on the bottom chords 35 of the cross bearer T, or other members. adjusting` bolts 79 being threaded on to the ends ot said l'ods Ti'. '.l`he uppcl ends ot' rods T are secured by pins or other `mitable means to connection lplates'S() which are bolted to the llanges ol the cylindrical tank sections or sheets 47.

The usual inlet tor the tank will. of course. beI provided. though it is not shown` and the outlet may consist oll the pipingr Si shown in Figs. l and il to best advantage. Conveniently included in the piping Nl is an outlet valve and the end ofthe outlet piping may be closed by a cap Ril.'
